But the Raiders on Saturday agreed to trade the 27-year-old to the Chicago Bears, ESPN's Adam Schefter reported, citing sources.

Just one month ago, the idea of the Raiders trading their best defensive player seemed impossible, but that all seemed to change over the past 24 hours.

The question is, with so much speculation going around, would the Raiders really acknowledge that they were considering a trade for Khalil Mack if they were, in fact, considering a trade for Khalil Mack? The Bears are already without their second-round pick next year from the Anthony Miller trade, so acquiring Mack would severely limit their ability to build through the draft.

Mack is entering his fifth and final year of his rookie contract and is expected to earn roughly $13.8 million this coming season but has been sitting out all offseason, preseason, and most likely will in the regular season. "The spotlight is very clearly on Jon Gruden", Rapoport said.

With The Los Angeles Rams signing Aaron Donald to a massive contract extension, the attention has now shifted to Oakland Raiders DE Khalil Mack. Mack believed he should be paid his worth as one of the best defensive players in the league. So you can see why Mack would not be inclined to play ball with the Raiders at this time.
